PHP Prático: Streams

A palavra stream significa corrente. Em geral, qualquer conexão de rede é uma stream, e existem vários tipos de protocolos para streams. Esses protocolos definem como os dados fluem na corrente.

No PHP, vários protocolos são suportados de forma transparente:

#!/bin/bash
for DIR in */ ; do
    if [ -d "$DIR/.git" ]; then

        cd $DIR
        BRANCH=$(git branch | sed -n -e 's/^\* \(.*\)/\1/p')
        
        echo "Atualizando: "$DIR "("$BRANCH")"
        echo "===================================================="
